An assembler for the HACK assembly language, implemented in C.

If you are interested in my learning process building this project, please see the extensive learning remarks in the /learning_remarks folder! In these files all original comments are removed and instead I have provided longer descriptions of specific challenges and how I grew by completing this project.

Structure

• assembler.c -> The main procedures.
• parser.c -> Helper functions for string manipulation, data sanitization, etc
• data.c -> Hardcoded data and lookup table
• table.c -> Linked list data structure and functions for symbol table

Testing is automated through test.sh. All sample programs and output references are in /programs.

Run it yourself

• git clone this repository
• In the base directory, gcc assembler.c
• The resulting a.out file is your assembler. You can pass HACK assembly code to it with ./a.out << file.asm and see the resulting binary in your terminal. To save the output to a file, ./a.out << file.asm >> output.hack.
